The parking lamps (10/11-12, 10/44-45 and 10/51-52) and license plate lighting (10/3) lights when:

the knob in the light switch module (LSM) (3/111) is in the low beam position
the knob in the light switch module (LSM) is in the parking lamp position
low beam is lit via the low beam automatic function (market dependent).

The central electronic module (CEM) (4/56) receives information from the light switch module (LSM) which is directly connected to activate the lamps.

The lamps are powered directly via two outputs on the central electronic module (CEM).

The license plate lighting, front parking lamp on the left-hand side and the rear parking lamp on the right hand side are supplied with power from one output. The front parking lamp on the right-hand side and the rear parking lamp on the left hand side are supplied with power from the other output in the Central Electronic Module (CEM).

To detect problems with the lamp faults, the central electronic module (CEM) reads the power consumption of each output.

The parking lamps have a limp Home function and will work even if there is a fault in the control area network (CAN) or an open-circuit in the serial communication between the light switch module (LSM) and the central electronic module (CEM). The parking lamps will function when the ignition key is in position II.
